Winpac provides outsourced back-end semiconductor services, the final manufacturing steps that mount a bare chip onto a circuit board, seal it against moisture and contaminants, and verify that it works correctly.
Its customers are chip makers and fabless designers (companies that design chips but do not manufacture them) who contract out these finishing steps. Listed on KOSDAQ, Korea's tech-focused small-cap exchange, Winpac handles both packaging and testing under one roof, a combination that most domestic back-end specialists do not offer, allowing customers to place a single order covering both services.
